Described as Cicada 6-notata Fallen.(Wilson & Claridge 1991)

Description & Identification

Small, slender species. male 2.90‚ÄĒ3.30 mm., female 3.40‚ÄĒ3.50 mm. (Nielson, 1968)General colouration yellow to yellowish green, sometimes with dark. markings enlarged on body, with. faint smoky tint on fore wings. vertex gently rounded anteriorly in male, rather deeply rounded in female; spot pattern often isolated or sometimes largely confluent. Frontoclypeus with dark transverse bands isolated, sometimes confluent or reduced partly. Anteclypeus parallel-sided in male, broader basally in female. Scutellum usually with basal spots.Male abdomen.: 2nd acrotergite with trunk widely V-shaped, broad triangularly produced ventrally; neck slender, shorter than half of trunk width. 2nd tergal apodeme reaching to near 2/3 of tergite posteriorly. 1st sternal apodeme with anterior lobes small, more or less truncate; posterior lobes slightly longer than wide, inclined in lateral aspect. 2nd sternal apodeme with posterior lobes short, about as long as or slightly longer than basal width. (Nielson, 1968)Male abdomen.: 2nd acrotergite with trunk widely V-shaped, broad triangularly produced ventrally; neck slender, shorter than half of trunk width. 2nd tergal apodeme reaching to near 2/3 of tergite posteriorly. 1st sternal apodeme with anterior lobes small, more or less truncate; posterior lobes slightly longer than wide, inclined in lateral aspect. 2nd sternal apodeme with posterior lobes short, about as long as or slightly longer than basal width.Male genitalia: Subgenital plates with 7-9 macrosetae about as long as apophysis of style, or slightly longer distally; apical processes roughly as long as commissure of plates. Aedeagal shaft gently narrowed distally, with microspines laterally andventrally; lateral flanges absent; apical processes divergentdistally in posterior aspect, meandered and curved anteriorly in lateral aspect, with proximal meandered part apparently shorter than distal part. (Nielson, 1968)This species is similar to laevis in male genital characteristics and can be distinguished by the triple bend of the aedeagus in lateral aspect. (Nielson 1968)


Biology & Ecology

Studies on the biology were reported by Tullgren in 1925 (791) and Rostrup and Thomsen in 1931 (649). Two to three generations occurred a year and the insect overwintered in the egg stage. (Nielson, 1968)

Worldwide Distribution

Widely distributed and common in the western Palaearctic.It is widespread in Europe and Asia. Records of this species in the United States were erroneous (Beirne 1952 [54]). Because of the voluminous records reporting the widespread distribution of this species, no attempt will be made here to record the various localities. Possibly many of the records actually referred to other species of Macrosteles, and until a thorough study of the taxonomy and biology has been made on the Palearctic fauna it seems best to retain a status quo position for the present.

Vector Status

This species is a vector of European aster yellows virus. It has been reported as a suspect vector of sugarbeet mosaic by Muraviov (539) and Novinenko (572), but this has not been confirmed. Posnette and Ellenberger (623) were first to report this species as a vector of delphinium yellows in England, Only 1 white clover plant out of 10 was infected with the virus. The authors reported that the species was probably an efficient vector of this virus as evidenced by the spread in the field.(Nielson 1968)This species is not considered an important vector in the natural spread of delphinium yellows in England.(Nielson 1968)
